The OP is asking about the one with the yellow ring, and I do believe this will activate the front parking sensors. I think you’re talking about the button on the top (the one with the pink ring around it in post #3).

No, when you select Sport+, you turn on DTC (dynamic traction control). Under normal circumstances this is deactivated, but DSC (dynamic stability control) is active. DTC is a mode that allows for more wheel slippage before DSC kicks in.
